Laparoscopic surgery is a technically demanding procedure that requires a significant level of experience and expertise. Since surgery is the mainstay treatment of rectal cancer, comprehending the complexities of multilaminar structures and interfascial spaces is imperative.

This is the case of a 68-year-old woman who was evaluated for a positive fecal occult blood test. Colonoscopy found a vegetative lesion 15 cm from the anal verge, occupying ~1/2 of the lumen. Biopsy and distal tattooing were performed. Pathology study confirmed the presence of a moderately differentiated adenocarcinoma.
The CT-scan showed no lung or liver metastasis. MRI revealed an upper rectal cancer, 11.4 cm from the anal verge, with no pathological lymph nodes, staged as cT2 N0 Mx CRM-.

After discussion in a multidisciplinary meeting, a laparoscopic anterior rectal resection was proposed.

By segmentation of the surgery into well-organized stages, this video demonstrates all the important technical steps to fasten the learning curve and master the procedure without compromising the oncologic principles.

In this video we present the case of a 98 year old chinese gentleman who presented to the emergency department for 2 days of painful right groin lump. He has a history of bilateral inguinal hernia for many years, but declined surgery. Otherwise, his past medical history includes degenerative disc disease, osteoporosis and hearing impairment. On presentation, he was able to tolerate oral feeding with no nausea or vomiting and still able to pass stools. On examination, there was a large and tender right irreducible inguinal hernia with overlying erythema and warmth. There was also a small left inguinal hernia that was reducible. CT Abdomen-Pelvis was done and showed an incarcerated right inguinal hernia containing a loop of sigmoid colon with poor enhancement of the bowel wall. The colon proximal to the incarcerated segment was also mildly dilated.

Patient underwent urgent repair of the strangulated right inguinal hernia via laparoscopic, transabdominal preperitoneal (TAPP) approach. Intra-operatively, a loop of sigmoid colon was incarcerated within a direct right inguinal hernia. A small colotomy had to be made to decompress the incarcerated loop in view of difficulty in reducing the sigmoid colon. After reduction, the incarcerated segment was gangrenous and non-viable requiring sigmoid colectomy with primary anastomosis. Pantaloon inguinal hernias with femoral hernias were seen over bilateral groins. An Ultrapro 10x15cm composite mesh was inserted over bilateral groins with adequate medial overlap ensured.

The operation took three hours and fifty minutes with minimal blood loss. Drain was removed and feeding was escalated to diet on post-operative day four. Patient was able to pass stools and then discharged on post-operative day six. His case was complicated with a small 2cm seroma at the right groin.

A 75-year-old male with history of chronic HCV- related hepatitis, in regular follow-up and sustained viral response (SVR), presented at our Emergency Department for sudden epigastric pain. Urgency CT scan and subsequent abdominal MRI revealed a 2,5cm monofocal HCC in S5 with surrounding hepatic hematoma (7cm of extension) and hemoperitoneum layer. The procedure consisted in laparoscopic exploration, lysis of tenacious adhesions between hepatic hematoma and the right colic flexure, intraoperative ultrasound to assess tumor extension, preparation of Pringle Maneuver and parenchyma transection with ultrasound dissector combined with colecistectomy.
